I have been having a discussion with another physics teacher who believes that
there is no voltage inside the sphere of a Van de Graaff generator.  I
know that the electric field is zero but believe the voltage is constant
and is the same as the surface value.
Being a high school teacher I have trouble remembering those equations
of thirty years ago.  You don't use it so you lose it.  The you being me.

I would appreciate you thoughts and an explanation to convince me that I
am wrong or ideas I can use to convince my friend that I am right.  Of
course I would be glad to learn the correct theory if both of us are
wrong.  It would not be the first time.

Thanks for your time and I do enjoy reading this list.
